QAV-M 114 // Babyhawk rebuild

Despite it being pink, which is usually an instant win in my book, I was always slightly disappointed by my Babyhawk, largely due to the complete lack of camera protection (I broke the camera on literally the second outing). So I figured I'd see if 3D printed PET-G was a plausible option for something this small & with such minimal weight.

I went with a R9 Mini simply because it's both smaller & cheaper than any of the 2.4GHz receivers from FrSky, even if the long dipole antenna is a bit awkward on such a smol frame.

Dry weight is 77g, so notably up compared to the ~64g of the Babyhawk, but ain't it just the cutest?

hey,
Nice colors :)
I'm building a similar, albeit smaller, micro and have annissue mounting the Foxeer arrow

Did you 'just' zip tie the camera? No seat nothing? And how can you angle it?

Thank you!

It was just zip ties to the top plate, which gave it a bit of upward tilt. It's not a great solution, it needs longer standoffs to allow more than a very acute angle because the camera/VTX is just too big otherwise.

video?

Neat! I wonder if you could just zip tie the antennas along the arms for better protection. It's not carbon and should not affect the antenna performance.

I tried & it didn't make much of a difference, still sticks out ~1" at either end.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
